DRUM AND SUCH LIKE VESSEL.

Specification of Letters Patent.

Patented July 30, 1907.

Application-filed May 5,1905. Serial No. 259,073.

To all 'uhom 1! may concm'n:

5e it known that I, \VAL'IER AsunY MITCHELL, a subjet'l of the King ofGreat Britain and Ireland, and a resident. of Dundee, in the county ofForfar, Scotland, (whose pnst-ollice address is Kings Cross, Dundee,)have invented a certain new and useful Improvement in Drums and SuchLike Vessels. (for which I have aplied for a patent in Great Britain,No. 5,522, bearing date 16th March, 1905,) of which the following is aspecification.

'lhis invent ion relates to drums and such like. vessels, the objectbeing to improve the aperture and the mode of sealing same. And in orderthat my said invention and the manner of performing or carrying the sameinto effect or practice may be properly understood, I have hereuntoappended an explanatory sheet of drawings in which the same referencenumerals are used to indicate corresponding parts in all the figureswhere shown; that is to say:-

Figure l. is a section through the head of an ordinary drum showing thecover in position. Fig. 2. is a similar view showing the cover ready tobe placed in position.

In (.'&ll'l' 'lll; out my invention, l form in the head A. of the drum.or such like vessel, a circular aperture of any desired size. the centerof such aperture being either concentric or eccentric to the axis of thedrum, or other vessel. This aperture is formed to have a rais d mal lipor head B. of any suitable depth. The cover t. is stamped with a femalebead I). which fits on to the male bead. that. is to say the cover whenplaced in position [its on to the female bead. At-

tached to the head are two or more sheet metal fingers or tabs E. whosefree extremities can be folded over the female head when the cover is inposition, thus keeping it secure. A handle F of the usual type may beattached to the cover, if desired.

The female head is of such shape and size relative to the male head thatwhen the cover is placed in position it binds hard all around, thereason being that the two heads are somewhat elastic. that. is theirouter edges can be forced apart and together.

The tabs keep the cover from being knocked out when any extra strain isput on it and because of the shape of the beads the inner bearingsurfaces at II. H. cannot; be destroyed.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is;-

In comhination with a can having a straight upper edge of a separatehead having its outer edge turned upwardly at right angles to the mainportion to form a flange for engaging with the upper edge. of the can,said head having a central aperture and the edge of the head around saidaperture being bent into inverted U form to form an elastic hollow head.a cover for said aperture having: its periphery bent to form an elasticbead corresponding in shape to the bead on the head and adapted to titover the same, tabs adapted to tit over the said beads and a handlesecured on the cover, the said handle and beads being of less heightthan the outer flange of the head.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
